WEATHER; STRIP OR ISEAL FOR SL IDING WINDOW-SASHES.

Specification of Letters Patent.

Application filed Ju1y.3, 1912. Serial No. 707,499.

for the purpose of opening and closing the window. a

Weather strips designed to prevent the entrance of air about the sides of window sashes are quite common, but notwithstancb ing the presence of such strips, considerable air willlbe admitted between themeeting faces of the top and bottom sashes, and it, is the purpose of this inventionto provide an effective and automatic sealing, of this space when the window is closed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of ref erence indicate corresponding; parts in all:

the views, and in which- Figure 1 shows a side elevationof the ends of a pair of window sashes, and also shows a portion of the inclosingframe, the

view being broken for convenience of illustration, and showing also the improved weather-strip and a latch for holding the upper sash from movemenh and showing the parts in the position; which they will have when the window: is, closed; Fig.2 is a simi* lar view to Fig. 1, showing the lower sash raised with relation to the upper sash sufficiently to release the latch holding the up-H per sash and preliminarily to thelowering of the upper sash; Fig. 3shows the upper sash lowered; Fig. 4 is afperspective view of a port-ion of the upper sash, and illustrating the latch for the upper sash and a por tion of one of the cooperating parts of the weather-strip, also showing a portion:of the inclosing window frame; Fig. 5 is a perspective view illustrating the operation of the swinging blade member of the weatherstrip, said member being broken away to show underlying parts; F ig.,.6 is a front elevation of the blade member, and also showing in dotted lines the operating device for said member; Fig. 1

sash, andillustrating the connection thereto of the operating device for the blade mom her; and F ig.8 is a top plan view of a portlon of the top of the lower sash.

In the drawings, A shows a windoww Patented Apr; 15, 1913 n is a vertical. sectional v1ewthrough the top of theilower frame, and B andB an upper and lower window sash, all of which, except as hereinafter set forth,n1ay be of any llSllillqOl ordinary construction, it being understood:

that the sashes B and B' have a movement along vertical guides b and Z) in the frame a A, andthat they are supported by counterbalanced weights (not shown) attached to flexible connections b, which pass ovcr pulleys b and areconfined within recesses 1n.

the frame A, all in. a manner which is well known.

The weather-strip comprises two members, one of wlnch Wlll be designated as the groove member C, it havmg at 1ts lower edge an up-turned flange a, forming a groove 0, to I'GCEIVQ the blade member, as Wlll be hereinafter set forth. The groove member C is made of some suitable thin sheet metal,.

and itis of a length approximating the length of the bottom of the upper sash; B, and is affixed to the front inclined face lfi,

by means of screws or other fastening devices 6 The blade member D is constructed of some suitable strong but resilient metal, and it is secured along its upper edge to the outer beveled face (Z of the lower sash B by means of screws (Z, or by any The lower edge of the blade member D is entlrely 1111-.

other suitable fastening means.

attached, and is free to be forced, outward away from the beveled faced in order that its :lower edge may enter the groove 0 of the groove member C, as clearly shown in;

Fig. l of the drawings. The blade member D is ofsubstantially the same length as the Y groove member C, and approximately of the length of the top of the lower sash B.

It is intended that the blade member D. shall be automatically moved outward away from the sash B as the windows approachl the closed position, so that the lower edge of the blademay enter the groove and effect the sealing of the space between the window sashes as theclosing operation is completed,

as shown clearly in Fig. 1 of the drawings.

To secure the automatic outward spring ing of the blade member D and its automatic returnrto anormal position, there are prov vided swinging levers E, which are pivoted at their lower edges by means of staples e, or by any other suitable pivotal means within a longitudinal groove or recess F formed in i the beveled face cl of the top of the lower sash B. The levers E at the ends adjacent the ends of the. top of the lower sash will be provided with. rearwardly-extending arms 6, arranged to be engaged by dogs or pawl's' e which are fastenedto the window frame in the pathof movement of the arms 6 and at such a point as to cause the levers E to be tilted to force outward the lower edge of the blade D as the lower sash approaches the closed position. The side pieces of the lower sash will be provided with verticallyextending grooves 6 to afford a clearance for the dogs 6 The foregoing arrangement is such that, the, upper sash being raised, the loweringof the lower sash brings the arms e into contact with the .dogs 6 and causes I the levers E to swing about. their pivots e and to spring, away from the sash G the blade D,'so that its lower edge will fit into the 'roove a of the groove member C, thus effectually sealing the space between the sashes, and preventing the entrance of air and dust particles. The raising of the lower sash automatically causes the blade D to resume its normal position.

Obviously it wouldbe unwise, if not impossible, to lower the'upper sash 13 until the lower sash had been .moved upward sufliciently to permit the blade D to resume its normal .or retracted position, and therefore there is provided a latch M for the upper sash, comprising a lever pivoted at m to the window frame A, andhaving at one end a down-turned toe m, arranged to fit into the sockets m in a latch platem fastened to the front of the window sash B, at one side thereof. This lever M is automatically moved to cause its toe m to, engage the sockets m in the socket plate m by means of a spring m, which is fastened at one end to a stud m and at its opposite end engages the lever or latch M; The lower end of the lever M is roundedupon its outer surface, and constitutes a cam, and when it is in locking engagement with the upper sash, this cam-like lower end isin the path of movement of the upper edge of the lower sash, so that the raisingof the lower sash ,sufliciently to cause it to engage the cam.-

like end m of the latch lever M, will result toe m from the latch plate m and thereafter the upper sashmay be lowered, or the "lower sash raised to any extent desired;

The operation of the weather-strip, it. is

thought, has been sufliciently set forth in connection with the foregoing; description of its construction and organization and a ,in the automatic withdrawal of the locking 1' further "description of. its operation will be found unnecessary.

claim as new and desire to secure by Letters Patent Having thus described my invention, Ii

1. A weather-strip or seal for the meeting edges of sliding window sashes, comprising a strip of sheet metal bent upwardly at, its

lower edge attached to the inner face of the bottom of the top sash, a blade member atmember carried by. one sash, and ablade member carried by the other sash, means to cause said blade. member to engage :the

groove member as the window sashes are closed, a spring latch for automatically lock ing the sash carrying jthe groove member and having a cam-like part projected into the path of movement of the window sash carrying the blade member, to be engaged thereby, to automatically release the latch.

In testimony whereof I have signed" my K name to this specification in the presence of two subscribing witnesses.
